Drivers seat cushion

I have a 1996 G.M.C. with blue captains chairs. The drivers side is starting to show its age and was wondering if anyone knows of a place that sells the identical replacement besides G.M. because I don't want to pay 3 times what it is worth.

I've been searching ebay for replacement for my 99 seats. Type in Chevy seats in the search on ebay and quick a few pop up. Finding the right color/year combo can be difficult though. A junkyard may also be your best bet if they have a wrecked one.....
